Current failure rate within the first three months of purchase is
17.2% (sample size 29, 5 failed)
We have tested a seven more devices since my last email that have
been at a site for 3 months (including flashing them to latest
version, enabling host mode and flashing a custom kernel), all worked
fine and we have one more failure at another site (version 2, no host
mode or custom kernel).
Of the failures 4 are the classic screen failure reported by many and
1 was dead out of the box (continuous reboot).
We only have one 800 which is still working fine.
I have started logging serial numbers to see if there is a higher
incident of failure with certain ones. 3 of the failures have nearly
identical serial numbers (last digit is different), two with similar
numbers last number different are still operational. The other two
failed units I don't have the serial numbers of. Leading me to the
suspicion that batches of 770s may be faulty - assuming 770s in the
same batch have very close serial numbers of course not enough data
to be conclusive.
I would give out the serial numbers of the ones that have failed but
Nokia are using the serial numbers as a sort of password to their
firmware so I guess they would prefer me not to. However if anyone
wants to send me their failed unit serial numbers I can see if there
is any correlation with serial numbers we have had fail.

Simon
